Shoe upper



FIG. 1 is top, right perspective view of a shoe upper showing my new design;

FIG. 2 is a rear perspective view thereof;

FIG. 3 is a top left perspective view thereof; and,

FIG. 4 is a top plan view thereof.

In all the views, the portion of the shoe shown in broken lines is for illustrative purposes only and forms no part of the claimed design. 

I claim an ornamental design for a shoe upper, as shown and described.
